How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a gaming-first headset built for competitive play — ultra-low latency wireless, a pro-grade boom mic, and console-focused spatial audio — choose Razer BlackShark V3; if you need a travel-ready everyday listening companion with marathon battery life, a folding frame, and music-tuned ANC, choose Marshall Monitor III A.N.C. These two look like they compete for the same ears, but they're really built for two different lives. One is esports hardware that happens to play music. The other is a music headphone that happens to take calls. Let me break down exactly where each one wins.
• Razer BlackShark V3 — biggest strength: A gaming toolkit no music headphone can match: 2.4 GHz HyperSpeed wireless with latency as low as 10 ms, a detachable 12 mm full band mic, and four ways to connect at once.
• Razer BlackShark V3 — biggest trade-off: It's heavier and more specialized. At 2.3 pounds it's built for a desk and a headset stand, not a jacket pocket, and its real magic only shows up on Xbox and PC.
• Marshall Monitor III A.N.C — biggest strength: Battery life and portability. Up to 70 hours with ANC on, 100 hours off, a foldable rugged frame, and a premium hard case make it the easier one to live with.
• Marshall Monitor III A.N.C — biggest trade-off: It's a listening headphone first. There's no detachable boom mic, no low-latency gaming transmitter, and its 32 mm drivers are tuned for music, not for pinpointing footsteps.
• Who each is for: Buy the Razer if you game on Xbox or PC and want to win. Buy the Marshall if you commute, travel, and listen to music all day.
The BlackShark V3 is, at its core, a competitive gaming tool. The headline spec is HyperSpeed Wireless Gen-2, which Razer rates for latency as low as 10 ms. That number matters more than it sounds: in shooters, audio that lags slightly behind the on-screen action can cost you a reaction. Wired and Bluetooth are fine for casual listening, but for ranked play the 2.4 GHz connection is the point. Pair that with the TriForce Bio-Cellulose 50 mm Gen-2 drivers, which are tuned specifically for clarity and positional accuracy, and you get a headset designed to tell you where an enemy is, not just to sound pleasant.
The second half of the pitch is communication. The detachable HyperClear Full Band 12 mm mic uses a unidirectional pickup pattern and a large capsule, which is exactly the kind of setup that keeps your voice clear while pushing keyboard clatter and room noise down. If you've ever been the person your squad can't understand, that's the fix.
Who should buy it: Xbox and PC players who want low-latency wireless, a serious mic, and game-specific audio tuning. Who should skip it: Anyone who mainly wants a music headphone for the train. The 2.3-pound weight, plastic-and-foam build, and lack of a folding travel design make it a stay-at-home rig, and its spatial features are largely wasted on a phone.
Marshall Monitor III A.N.C: Who It's For
The Monitor III A.N.C. is a different animal entirely. Marshall's focus here is stamina and daily life. You get up to 70 hours of wireless playtime with active noise cancellation running, and up to 100 hours with it off — figures that put most over-ear headphones to shame and mean you can genuinely take a week-long trip without packing the USB-C cable. Charging back up takes about 2.5 hours when you do need it.
The noise cancellation itself has been upgraded from the previous generation, and Marshall added continuous ambient-noise measurement so the ANC adapts to your surroundings. There are three cancellation levels plus a Transparency mode, so you can dial in how much of the world you let through. That's a commuter's feature set: block the train, hear the platform announcement, then block it again.
Sound is handled by 32 mm dynamic drivers with a warmer, more musical voicing and Dynamic Loudness, which rebalances treble, mids, and bass at every volume so the mix doesn't collapse when you turn things down. Soundstage spatial audio widens the presentation beyond your head. The build is the other half of the story: a rugged, foldable frame that ships with a premium hard case, soft ear cushions for long sessions, and button controls backed by an app. On the spec sheet the Marshall is noticeably lighter at 14.24 ounces, and it's the one that folds flat and disappears into a bag.
Who should buy it: Travelers, commuters, and anyone who listens to music or takes calls for hours at a time and wants one pair to do it all. Who should skip it: Competitive gamers. There's no low-latency transmitter, no detachable boom mic, and no game-tuned EQ — the built-in mic is for calls, not for shotcalling.
• Best for competitive gaming → Razer BlackShark V3. 10 ms-class 2.4 GHz wireless, positional 50 mm drivers, and pro FPS EQ profiles are built for exactly this.
• Best for battery life → Marshall Monitor III A.N.C. Up to 70 hours with ANC on and 100 hours off beats the Razer's 70-hour rating with a clear margin when noise cancellation is in play.
• Best mic for voice chat → Razer BlackShark V3. A detachable 12 mm unidirectional full band boom mic is in a different league from a built-in call mic.
• Best for travel and commuting → Marshall Monitor III A.N.C. Foldable, rugged, lighter at 14.24 ounces, and shipped with a hard case.
• Best for Xbox and PC spatial audio → Razer BlackShark V3. Windows Sonic on Xbox and THX Spatial Audio 7.1.4 on PC, plus app-based EQ saved to the headset.
• Best for casual everyday listening → Marshall Monitor III A.N.C. Dynamic Loudness and Soundstage spatial audio keep music sounding full at any volume.
• Best for device flexibility → Razer BlackShark V3. Four connection modes, including mixing 2.4 GHz and Bluetooth from two devices simultaneously.
• Best for long-wear comfort on the move → Marshall Monitor III A.N.C. Soft ear cushions and a much lighter, foldable frame.
If I had to pick one, it comes down to what you actually do with headphones. For gaming, I'd buy the Razer BlackShark V3 without hesitation — the low-latency wireless, detachable boom mic, and Xbox/PC spatial audio are advantages the Marshall simply doesn't try to match. But if your headphones live in your bag and your priority is music, podcasts, and calls across a long week, I'd take the Marshall Monitor III A.N.C for its battery life, lighter foldable build, and travel case. In my opinion, neither is a compromise — they're just aimed at different owners. Pick the one that matches your day, not the spec sheet.
FAQ
The Razer. It's the only one of the two with a 2.4 GHz low-latency connection rated as low as 10 ms, a detachable 12 mm boom mic, and console/PC spatial audio. The Marshall is a music headphone with a call mic, not a gaming headset.
Yes to both, with caveats. The Marshall has a built-in mic for calls plus a USB-C to 3.5 mm cord for wired listening. The Razer plays music fine over Bluetooth 5.3 and 3.5 mm, but its tuning and features are aimed at games.
The Marshall. It folds, ships with a hard case, weighs about 14.24 ounces, and lasts long enough to leave the charger at home. The Razer is heavier at 2.3 pounds and built to stay at your desk.
